テープである。The invention according to claim 1 is an adhesive tape comprising a polyolefin layer formed on one surface of a nonwoven fabric and an adhesive layer formed on the other surface thereof, wherein the nonwoven fabric is a fiber. Of which at least a part is made of polyester or polyolefin, and the arrangement of the fibers has an aspect ratio of 1:
A pressure-sensitive adhesive tape comprising a non-woven fabric of 1 to 8: 1 which is subjected to a heat compression treatment in a portion having an area ratio of 15% or more.

支持体が破断してしまう恐れがあるからである。The ratio of the fibers arranged in the longitudinal direction to the fibers arranged in the lateral direction must be 1: 1 to 8: 1. When the vertical arrangement is less than 1 with respect to the horizontal arrangement 1, the vertical elongation when formed into an adhesive tape becomes too large and the sticking workability is deteriorated.
If it exceeds, the longitudinal elongation is excessively suppressed, the stress relaxation of the support does not work sufficiently at the time of re-peeling, and the support may be broken at the time of re-peeling or unwinding.

は２０〜１００％が適当である。It is necessary to subject the non-woven fabric to a heat compression treatment on a portion having an area ratio of 15% or more. By performing this heat compression treatment, elongation of the non-woven fabric can be suppressed, and preferably 20% or more. Need. The heating and compression area of the non-woven fabric is about 20 for architectural painting and electrical insulation.
30%, about 25-28% for sealing and 20-100% for vehicle coating are suitable.

からである。The polyolefin layer formed on one surface of the nonwoven fabric is formed by laminating polyethylene, polypropylene, etc.
The thickness is about 25 μ. If it is less than 8 μm, the rigidity of the support will be too weak, and if it exceeds 25 μm, the rigidity will be too strong.

る。The content ratio of SIS, which is the main component of the pressure-sensitive adhesive, and natural rubber is 25:75 to 80:20 by weight. The reason is that if SIS is less than 25 parts by weight, adhesive residue will occur during re-peeling. This is because if it exceeds 80 parts by weight, the wettability becomes small and the tackiness is not sufficiently exhibited.

Examples include rosin-based resins such as rosin esters, terpene-based resins, terpene-phenolic resins, coumarone-indene resins, various petroleum resins, and styrene-based resins. The addition amount of this tackifying resin is preferably 20 to 70 parts by weight based on 100 parts by weight of SIS and natural rubber. If it is less than 20 parts by weight, the tackifying function is not sufficiently exhibited, and if it exceeds 70 parts by weight, the Tg (glass transition temperature) is increased, so that the adhesive residue is likely to remain even at room temperature.

-40 parts by weight is preferred. This is because if the amount is less than 2 parts by weight, the wettability becomes small and the tackiness is not sufficiently exhibited, and if the amount exceeds 40 parts by weight, adhesive residue tends to remain.

できる。As described above, the pressure-sensitive adhesive tape of the present invention is inherently hand-cuttable, and the fibers are arranged in a length: width ratio of 1: 1 to 8: 1. The hand-cutting strength can be adjusted by changing the heat-compression ratio, changing the heat-compression ratio, etc., making it easier to design the quality of the adhesive tape depending on the application. Also, the waist is very flexible and can be placed within a few cm of the adherend. Since it is attracted and temporarily attached to the adherend, it can be peeled off as many times as necessary before the pressure is applied to correct the attachment position.
